Some loose, and perhaps idiosyncratic, ideas on what to get (see websites for current prices; see other threads here for more info and opinions) ... and I'm probably forgetting some stuff:
Table or bench: Use one you have, or get one made for the purpose that's also portable (sort of). That Holmenkol one people have talked about looks cool.
Vise: Some variant of the Skiman vise. Or make your own adapter.
Base edge guide: Beast. SVST Final Cut if you want to spend money.
Side edge guide: SVST aluminum. With shim(s) if you want to do more than one angle. You don't necessarily need the whole set ... you could, for example, do 1 and 3 degrees with a 1-degree guide and a 2-degree shim.
Stones: Set of two to four Moonflex diamond stones. Perhaps add (or substitute) a fine ceramic or natural polishing stone.
File: Get by with a single 8" file, but one of the ones from a places that sell ski stuff.
"Secret" sauce: Try rubbing alcohol and water 50-50. If you want, you can use vodka. Or gin, which imparts an appropriate piney scent.
True bar: Doesn't have to be real fancy.
Wax iron: The chepaer ski ones don't cost a lot and are an improvement over a retired clothes iron. A clothes iron will work, but requires more attention to avoid overheat.
Plexi scraper: Doesn't have to be fancy. I prefer the thinner ones.
Brushes: At least one nylon, probably also brass/bronze and horsehair.
